Yes, I used the Rikon 13-926 DVR motor upgrade kit.

It was not cheap, about $600 IIRC (looking at their site just now looks like $699US from Striatech, slightly less at other sources). The 1.75HP/1250W motor kit from Striatech is available with either a NEMA 56C or B14 Metric motor frame.
So between that and what I paid for my 10-325 I spent as much as the newer 10-326DVR bandsaw, actually probably a little more when you throw in that I upgraded the guide bearings to the new style that are on the 10-326. During the course of upgrading my BS I went over everything. My BS now runs rock steady and smooth. It has more power, MUCH more, and variable speed from 50 to 4000 FPM where before it was a choice of one of two speeds on a stepped pulley.
So I would say looking at it purely from the numbers, if you already have the 10-325 the upgrade might be worth it. I do believe it would be possible to mount the DVR motor on another brand saw. You would most likely have to adapt the mount, but that shouldn't be too tough.
The DVR motor kit is made by Striatech for Rikon.

I decided to take the chance of the Rikon upgrade kit as I have the NOVA DVR Lathe and it has performed over the 10+ years I have owned it. And NOVA has stood behind the tool. I contacted them once about 8 years after I got the lathe when I found out there was an upgrade to the control board. After sending them my serial number they sent me a new control board which was easy to install, simple plug and pray and I was up and running in 10 minutes.
Do a Google search on "
